WILLIAM L. 4ANG-EL, 0F PORTLAND, OREGON GAUGE FOR PRINTING PRESSES Application Ied April 25,

My invention relates to gauges for printing presses, the purpose and object of which 1s to align the paper in precise position relative to the platen upon which the printing 1s to be done.

One of the objects of my invention resides in a construction in a device that may be easily and quickly applied, that is self-contained, that is self-locking, and that will occupy a minimum of space, and be of minimum first cost. Y y

A further object of my invention resides in the construction that permits of the slitting of the platen paper by the device, when the paper'is stretched over the platen ofthe printing press. Afterpthe platen paper is slitted the device is then placed in the precise loca ,tion within the slit to locate the paper to be printed upon. t 5

. Heretofore in the constructions employed, there has been a tendency for the sheet of paper to engage under the gauge, therefore preventing the precise positioning and location of the paper relative to the type and to the gauge. It has also been necessary to make the slit for the gauge by a pen knife or by other means, but through the use of my device the slit in the tympan sheet is made by the gauge itself and after the slit has been made the gauge may then be placed in precise position and clamped by the clamping v.element disposed within thejgauge itself.

A. further object of my new ,and improved gauge consists in a devicethat may be easily adjusted when Aplaced in precise position, one that will prevent the paper to be printed from engaging beneath the stop wall of the gauge and one that may be made relatively cheapin first cost. I y

lVith these and incidental objects in view, the invention consists in certain novelA features of construction and combination of parts the essential elements of which are set forth in the appended drawings, and a pre` ferred form of embodiment o fwhich is here' inafter shown with reference to the drawings which accompany and form a part of this specification;

Like referenceL characters refer parts throughout theA several views.

I preferably form my device ofv two body elements l and 2 and hinge the same .together about a central journal p'in'3. Hinging ears 4 and 5 being formed in the body element l, and the hinging ear 6 being formed iin the bodyA element 2. The width of thefhinging ear 6 being sufficient to form a precise work`v ngrelavtionship between the spaced ears 4 and 5 formed within the oppositely disposed body element, so that when the hinging Aear 5 is placed in position, asillustrated'in Fig. 6, a device is formed that willv articulatein precise alignment lcaused by` the engaging ofthe side wallsof` the respective hinging ears. A stop head 7 is formed on the front end of thebody-element l, having a downwardly `ertending central stop 8 formed therein, and havingV side Walls 9 and 10. fThe stop head 7 and the body element l are made from a single piece 'ofmaterialfand is yso shaped that whenthe stop head 7 is formed 10o .te .like

of the mechanism il l Asurface of the body element 2.

substantially vertical to that of the body portion; the stop portions 8, 9, and 10 will extend below the lower surface 11 of theV body element 1. The body element 2 being formed of a double reverse curve 12, beveled on its lower side, as illustrated at 13 to form cutting edges 14 disposed at each corner.

When it is desire to place the' gauge within the tympansheet 15, the cutting edge 14 may be used to cut the slit 16 in the tympan paperv through which the gauge is to be placed. During the slittingand placing of the gauge in position the gauge is in open position as illustrated in Fig. 6.A A clamping lever 17, is rotatably mounted relative to the body element 1. The placing of the lever 17 through an opening 18 disposed in the body element l so that the camming surface 19 of the camming lever 17 may be made to engage upon the camming surface 20 upwardly extending from the body element 2. Cammingsurfaces 19 and 20 engage each other. The body elements 1 and 2 lare p artially rocked about the journal pin 8 until the tympan sheetc15v 'is held between the ends 21 and 22 of the body elements 1 and 2. With the stop wall 8 ofthe body element 1, engaging or piercing the platen paper so that it is 'impossible for the sheet to be printed going beyond the stop wall 8 or passing thereunder. A stop notch 23 upwardly extends from the body element 1 against which the cammingy lever 1.7 maycome to re'st and be held locked relative to the body element 1. A guide bar 24 passes through an opening 25 disposed within'the stop wall 8 and passes through the opening'26 in the body element 1 and comes to rest upon the upper The guide bar may be relatively locked in lposition 1 and 2 by having the inner end of the guide engaging with one or the other of the body Velements 1 and 2 or by securing the same by rivets or otherwise to either of the body elements.

and described is admirably adapted to fulfillV the objects primarily stated, it is to be understood 'thatit is not intended to confine the invention to the one' form of embodiment herein shown in various forms, all coming within the scope of the claims which follow :V
